Which EIGRP K-values are set to zero by default? (Choose three.)

EIGRP uses K-values to calculate the composite metric, which determines the best path to a destination. By default, K1 (bandwidth) and K3 (delay) are set to 1, meaning they are used in the metric calculation. K2 (load), K4 (reliability), and K5 (MTU) are set to 0 by default, meaning they are not used in the default metric calculation. While these K-values can be modified to include load, reliability, or MTU in the metric, doing so requires careful consideration as it can lead to routing instability if not consistently applied across all EIGRP routers.
